Morgan Stanley: A-Shares Enter Counterattack Window, Hong Kong Stocks May Regain Momentum in September
Nashnova编辑部
Morgan Stanley recommends taking profit on Hong Kong's earlier rally and rotating back into A-shares, arguing that the AI super-cycle plus A-shares' hard-tech concentration offer greater upside; Hong Kong needs September's dense tech catalysts to re-ignite.
Why is Morgan Stanley switching from Hong Kong to A-shares now?
The three reasons Morgan Stanley turned bullish on Hong Kong in early July — Q2 earnings bottoming, easing internet price wars, and Big Tech's LLM ecosystem progress — have now been fully priced in.
This means → Hong Kong's short-term "expectation gap" has narrowed, and the risk-reward of holding has weakened. Capital needs to find the next market where upside is not yet reflected.
At the same time, stabilising global markets and a returning AI capex cycle are creating a resonance effect for A-shares — Morgan Stanley sees the counter-attack window there, not in Hong Kong.
What structural edge do A-shares actually have?
Far higher hard-tech density than Hong Kong: semis, electronics, tech hardware, and telecom equipment account for roughly 42% of CSI 300 by weight, versus just 13.6% in MSCI China and 8.4% in the Hang Seng Index.
In plain terms = A-shares are the natural "home court" for AI and advanced manufacturing themes. Every extra dollar of global AI capex benefits A-shares with greater leverage than Hong Kong.
The liquidity squeeze from large tech IPOs — including CXMT and Unitree Robotics — is fading. Data show that in the five most recent tech IPOs above RMB 10 billion, average daily turnover share dropped about 0.5 percentage points in weeks 2–4 post-listing; as that pressure eases, market breadth should recover.
The "national team" is also stepping up: during the global AI sell-off in July, passive fund inflows into China turned positive again, and state-linked net buying of CSI 300, CSI 500, and CSI 1000 ETFs all expanded.
Are valuations cheap or expensive right now?
MSCI China trades at 10.7× 12-month forward P/E — price-to-earnings ratio, a gauge of how much investors pay per unit of profit — carrying a roughly 6% premium to MSCI Emerging Markets.
Against developed markets, the discount is still wide: S&P 500 sits at 19.7×, TOPIX at 16.0×, MSCI Europe at 14.9×.
CSI 300 trades at 13.2×, a roughly 23% premium to MSCI China. This reflects A-share investors pricing in higher growth expectations for domestic hard-tech sectors.
What could re-ignite Hong Kong in September?
The tech catalyst calendar is packed: Tencent's Global Digital Ecosystem Summit + WeChat AI launch, Alibaba's Qwen 4.0 upgrade + Apsara Conference, Baidu's potential dual-primary listing and Stock Connect inclusion, plus new model releases from MiniMax and Z.AI.
This means → around late September, Hong Kong's tech sector faces a concentrated "event-driven" window. If product launches beat expectations, capital could rush back in.
Fiscal ammunition is ample: Morgan Stanley estimates that as of end-July, unused quotas from government bonds and new-style policy financial instruments total roughly RMB 1.2 trillion. If macro conditions deteriorate, this fiscal space can be activated quickly.
How serious is the September lock-up expiry pressure?
September 2026 will be the largest month for Hong Kong IPO lock-up expiries in the past five years.
Morgan Stanley judges the overall market impact will be limited, but IT and materials will bear the most concentrated supply pressure — together they account for 66% of Hong Kong's H2 2026 lock-up expiry value.
In plain terms = the expiry is not a blanket negative — it is a structural one. If you are overweight tech and materials in Hong Kong, watch for this selling wave ahead of time.
Is foreign-investor positioning the key variable?
Foreign ownership of A-shares as a share of total and free-float market cap has not meaningfully recovered; the underweight posture persists. In Hong Kong, global and EM active funds narrowed their China underweight slightly in July, but active money overall is still in net outflow.
Year-to-date 2026 net foreign inflows stand at roughly 50% of the full-year 2025 level, and remain dominated by passive flows.
This means → the marginal driver of incremental capital is index-level passive allocation acting as a "floor," not strategic repositioning by active investors. Whether the market can graduate from a bounce to a trend depends on a substantive shift in active foreign-investor sentiment.
